(Sost−/−/Scid) were generated by crossing
Sost−/− mice (22 (link)) with B6.CB17-Prkdcscid/SzJ Scid mice (Jackson laboratories, Bar
Harbor, Maine, USA). Six-wk-old Sost−/−/Scid and
control littermate mice (wt/Scid) were injected intratibially with
105 human JJN3 myeloma cells or saline and sacrificed 4wks later
(6 (link)). Six to 10 female and male mice
per group were used for these experiments. Six-wk-old immune-competent
C57BLKaLwRij (23 (link), 24 (link)) mice were injected intratibially with
105 murine 5TGM1 myeloma cells or saline. After four weeks, tumor
engraftment was confirmed, mice were stratified by IgG2b levels, and then
control mice and mice bearing MM were treated with either Scl-Ab (15mg/kg/wk) or
control antibody (IgG) for four additional weeks, when the mice were sacrificed.
Seven to 10 female and male mice per group were used for these experiments.
Sample size for these studies was calculated based on previous studies (6 (link), 25 (link)). Mice were fed with a regular diet (Harlan, Indianapolis, IN),
received water ad libitum, and were maintained on a 12-hour light/dark cycle.
Studies were approved by the Institutional Animal Care and Use Committee of the
Indiana University School of Medicine.
